Help positioning Bose 10.2s

I inherited some Bose 10.2 ii's. they have the side firing mid, a tweeter that fires at 45 degrees and and second tweeter (that doesn't seem to put out as much as the fisrt) facing back (90 degrees). the sweet spot seems to be in the middle of course, at 45 degrees. my sitting position is further back (appx 60 dgrs), where i currently notice a drop in quality. My question is should i turn them so the 45 degree tweeter is pointing at my seat? With the bass ports and with the second tweeter now pointing about 30 degrees toward the side wall, is this a good idea? thx
